The Britain's Got Talent group have agreed a contract with Simon Cowell's Syco label, according to The Sun.
The band have built up a large Twitter fanbase since they performed self-penned tracks including 'Lovesick' on the show.
Eddie Brett is quoted as saying: "We're buzzing. This is everything we've been working towards. We are so happy."
Sonny Jay added: "Syco is a fresh label working with some great acts."
A source at Syco stated: "Syco have high hopes. They're the full package. They've got the look, the sound and were writing quality music before they'd even hit the studio. With One Direction and The Wanted doing so well, there is more than enough appetite in the market for male groups making good pop music."
Loveable Rogues follow Jonathan & Charlotte, who were also signed by Syco last month.
The band finished in fourth place in the grand final with 5.7% of the vote.
